If the user tries to run a program that doesn't exist from Bash, the
program name is looked up in a database that maps to Nix package
names. If it is found, we print out a message like:
$ pdflatex
The program ‘pdflatex’ is currently not installed. It is provided by
several packages. You can install it by typing one of the following:
nix-env -i tetex
nix-env -i texlive-core
If the environment variable $NIX_AUTO_INSTALL is set, the command is
installed and executed automatically:
$ hello --version
The program ‘hello’ is currently not installed. It is provided by
the package ‘hello’, which I will now install for you.
installing `hello-2.8'
hello (GNU hello) 2.8

To use this, you must currently manually put the SQLite programs
database in /var/lib/nixos/programs.sqlite. In the future, this file
should be provided as part of the NixOS channel so it gets updated
automatically. To get a test version:
$ curl http://nixos.org/~eelco/programs.sqlite.xz | xz -d > /var/lib/nixos/programs.sqlite
The new configuration.nix option 'environment.enableBashCompletion'
determines whether bash completion is automatically enabled system-wide
for all interactive shells or not. The default setting is 'off'.

Note that for attribute-based nix-env installations, the NixOS
channel contains Nixpkgs as its "pkgs" attribute, so
$ nix-env -iA nixos.pkgs.foo
will work instead of the old
$ nix-env -iA nixpkgs_sys.foo
* Fix the path to root's channels installed in ~/.nix-defexpr.

* Add a slash to the end of $MODULE_DIR, as expected by depmod. (Not
that running depmod from the command line is all that useful, since
you can't use it to update the tree in the Nix store. But at least
commands like "depmod -n" work now.) Reported by Kirill Elagin on
IRC.

window in which /bin/sh is missing. This can cause concurrently
running programs to fail (e.g. Hydra jobs =>
http://hydra.nixos.org/build/2267831). You'd think the odds of this
are very low, but they're not.

Users who want a user-specific bin directory to override system paths should
configure that in their user-specific ~/.bashrc, not in the system-wide init
file. The global file shouldn't add directories from user homes to $PATH
without knowing whether those actually exist or whether the users even want
them in $PATH. On my system, for example, there is no ~/bin, so I don't want my
$PATH to look for one. Removing an erroneous entry from $PATH is cumbersome,
but adding one is easy, so it feels better to err on the side of caution.

pierron recommended the use of types.string over mergeOptionString, as
it is superior but might break things.
For my system the change evaluated to the exactly same.

* Moved bash-specific code from /etc/profile to /etc/bashrc.
* Moved general Bourne shell code from /etc/bashrc to /etc/profile.
* Added "include guards" to both files to ensure that they aren't sourced
multiple times (which would result in lots of redundancy in $PATH, etc.).
* Both files include each other to make sure that the correct system
environment is always defined.
* When the current user has installed the 'bash-completion' package in her
$HOME/.nix-profile, programmable completion is automatically enabled in
interactive shells.
* The /etc/skel/.bashrc we installed has been dropped because it is redundant.
